🔧 Temporary Workarounds

Restrict access to deleteTicket.php

all

Implement access control at web server level to restrict who can access the vulnerable endpoint.

# Apache: Add to .htaccess
<Files "deleteTicket.php">
    Require valid-user
    Require ip 192.168.1.0/24
</Files>
# Nginx: Add to server block
location ~ /deleteTicket\.php$ {
    allow 192.168.1.0/24;
    deny all;
}

Disable delete functionality temporarily

linux

Comment out or remove delete functionality until proper fix is implemented.

# Rename the vulnerable file
mv deleteTicket.php deleteTicket.php.disabled
# Or add exit at top of file
echo "<?php exit('Service temporarily disabled'); ?>" > deleteTicket.php

🧯 If You Can't Patch

  • Implement strict network segmentation and firewall rules to limit access to the application.
  • Enable detailed logging and monitoring for all delete operations and set up alerts for suspicious activity.

🔍 How to Verify

Check if Vulnerable:

Attempt to access /deleteTicket.php without proper authentication. If it allows deletion operations, the system is vulnerable.

Check Version:

Check application files or admin panel for version information. Typically found in config files or footer.

Verify Fix Applied:

Test that /deleteTicket.php now requires proper authentication and authorization before allowing any delete operations.

📡 Detection & Monitoring

Log Indicators:

  • Multiple DELETE requests to /deleteTicket.php from unauthorized IPs
  • Failed authentication attempts followed by successful delete operations
  • Unusual patterns of booking deletions

Network Indicators:

  • HTTP POST/GET requests to /deleteTicket.php without proper session tokens
  • Traffic spikes to delete endpoint

SIEM Query:

source="web_logs" AND (uri="/deleteTicket.php" OR uri LIKE "%/deleteTicket.php%") AND (response_code=200 OR response_code=302) AND NOT (user_agent="monitoring_tool" OR src_ip IN [authorized_ips])
